Synopsis
High pressure aloft over the region will weaken over the next
several days as an upper-level trough over the pacific northwest
brushes the area. A cooling trend will develop as onshore flow
strengthens and night through morning low clouds return to the
beaches and possibly to the valleys through Thursday.

Short term (tdy-thu)
onshore trends today and a cooler air mass overall will lead to a
cooling trend all areas today and this is already reflected quite
well in the temperature trends this morning. Forecast looks about
right so not planning on any changes at this point. Still looking
good for low clouds filling in at least up to ventura county
tonight as an eddy spins up and the marine lyr deepens.

***from previous discussion***
there will be a little sundowner tonight. It will likely not
produce advisory level gusts. It will keep the stratus away from
the south coast. The rest of the coasts and lower coastal vlys
will see stratus clouds as the result of a decent sized eddy
spinning up.

There will not be too much change over the course of Wed and thu.

At the upper levels the flat flow will turn anti cyclonic as a
small east pac ridge moves closer to the coast. This will create a
few degrees of warming across the interior on Thursday. The strong
onshore gradient will combine with the eddy to bring low clouds to
all the coasts and most of the vlys. There will be a strong
onshore push both Wed and Thu and this will produce slower than
normal clearing across the coasts and vly and no clearing at the
beaches. The clouds and enhanced sea breeze will lead to two days
of blo normal MAX temps for the coasts and vlys.

Long term (fri-mon)
the little ridge peaks Friday morning and then is knocked down by
a little upper trof which will move through and then exit the area
later Saturday afternoon. Weak ill defined flow then sets up over
the state and the jet stream moves north.

Look for a little warming Friday then a little cooling on Saturday
and then two days of persistence Sun and Mon with MAX temps right
near normal.

The night through morning low cloud pattern will persist through
the period as the onshore flow will continue through the period.

The only question mark is how much penetration it will have. The
hgts are rather high and this might limit the inland penetration
of the low clouds.

Aviation 27 1000z...

at 01000z, the marine inversion at klax was based near 500 feet.

The top of the inversion was 2100 feet with a temperature of
29 degrees celsius.

Overall, moderate confidence in 12z TAF package. Current lifr
conditions at ksmx ksbp should dissipate by 17z withVFR
conditions for all sites this afternoon. For tonight, high
confidence in return of stratus fog to ksmx ksbp, but only
moderate confidence in timing. For sites south of point
conception, moderate confidence in return of ifr conditions to
coastal TAF sites, but low confidence in timing (could be
+ - 3 hours of current forecasted arrival time).

Klax... Moderate confidence in 12z taf. High confidence inVFR
through this evening. For tonight, moderate confidence in return
of ifr conditions, but low confidence in timing (+ - 3 hours of
current 08z forecast).

Kbur... High confidence in 12z taf. There is a 10-15% chance of
MVFR vsbys after 10z.

Marine 27 900 am.

High confidence in small craft advisory (sca) conditions from the
central coast to san nicolas island through at least Friday, and
will extended the current scy each day. Moderate confidence in
low end scy conditions over the santa barbara channel this
afternoon and tonight. There will be lulls each morning within 10
miles from the coast.

Two distinct wave types will be observable over the waters, and a
short period (6-8 second) west swell and or wind wave. The buoys
will likely highlight the long period swell at times, but the
short period swell will be most noticeable and will be highlighted
in the forecast. By the middle to end of the week, the short-
period west swell will dominate as the south swell fades.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect from 3 pm this afternoon to 3
am pdt Wednesday for zones 645-650. (see laxmwwlox).
